D. A switch increases collision domains
Each switchport represents a collision domain, unlike hubs where all ports form a single collision domain.
B should be the correct answer as the question was what is an ADVANTAGE of utilizing a layer 2 switch RATHER than a hub. Layer 2 switching is used for work group connectivity and network segmentation (breaking up collision domains).
